Paper tube curling device

Abstract

The invention discloses a paper tube curling device. A curling mechanism comprises an upper curling mechanism and a lower expansion mechanism; the lower expansion mechanism comprises a pressing plate,outward expansion plates, a spring ring, screws and nuts; the pressing plate is positioned at the bottom; the pressing plate is circular; four moving grooves are formed in the edge of the pressing plate at equal intervals; the outward expansion plates are positioned on the upper part of the pressing plate; the outward expansion plates comprise upper plates, lower plates and vertical plates; the upper plates and the lower plates are fixedly connected by the vertical plates, so that a groove is formed between the upper plates and the lower plates; the screws are arranged vertically; the tops ofthe screws are fixedly connected to the lower plates; the bottoms of the screws penetrate through the moving grooves; the nuts are positioned under the lower part of the pressing plate and are in threaded connection with the screws; the nuts fix the pressing plate to the lower parts of the lower plates; the four screws and the four nuts are arranged in correspondence with the moving grooves; thefour outward expansion plates are adjacent to each other to form a circular ring; the spring ring is positioned in the groove formed by the upper plates and the lower plates; and a through hole is formed in the middle of the four outward expansion plates. The paper tube curling device realizes efficient curling through the upper curling mechanism and the lower expansion mechanism.

Description

technical field [0001] The invention relates to the field of paper tube processing equipment, in particular to a paper tube crimping device. Background technique [0002] Paper tube refers to a tubular object processed by paper products. Most of the paper tubes are spiral tubes and seamless paper tubes. The difference in the material structure of the paper tube can make the paper tube have strong pressure resistance and be guaranteed during transportation. The paper tube can be customized with various patterns and styles, and the design is flexible, and the beautifully designed paper tube can often serve the whole It adds a lot of color to the product, and can even make the product look more high-end and refined. [0003] In order to meet the requirements of various designs, the paper tube needs to be processed. In the process of paper tube processing, the curling of the paper tube is an important part. The quality of the curling can reflect the quality and grade of the pap...
